yeast starter

[fadedgiant04]

Quick question. I have a pack of liquid ale yeast(1028) packaged on 11/6/2013. I want to do a 11 gallon batch this weekend of a gravity of 1.042. Beersmith says i need a starter with 2 yeast packs. what is the best way to use only one pack. Is it to make a reaaalllly big starter tonight then on friday decant and pitch with slurry calculations, or is it something different?

Thanks in advance.

If your equipment permits it, you can do one big starter. If not, make a 2 step starter.

How of you calculate that?

I saw a really good talk on You Tube at NorthernBrewer by a guy from WYEAST. He described how to determine pitch rate base on *Plato but had a easy conversion to SG. After seeing it I really understand how important pitch rate is. Ck it out: [ame]http://youtu.be/lEkwp_2Yezo[/ame]
